Application led April 19, 1915. Serial No. 22,395.

To all whom, it may concern.'

Be it known that I, EDWIN V. NESSLING, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for rFying Objects with `Wire; and I do hereby declare l the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for tying objects with wire and relates more particularly to certain improvements in specific details of construction capable of conjoint use and adapted and intended to be used conjointly with improvements in said machines invented by Rogers M. Warwick and particularly described and claimed in his application for Letters Patent of the United States Ser. No. 9962, filed Feb. 23, 1913, and to be similarly used conjointly with certain improvements in object carriers for machines for tying objects with wire constituting the joint invention of said 1rWarwick and myself," and described and claimed in an application for Letters Patent of the United States Ser. No. 22,374 filed April 19, 1915.

rLlhe particular objects of the present invention are:

First. To provide, in a machine of the character defined, means controlled by the object to be tied for maintaining the tying mechanism inoperative to tie objects unless such objects are properly presented to the same; f

Second. To provide wire-guide supporting means for machines or' the character delined relatively so arranged and operated with respect to the plane in which the tie is formed and with respect to the path of travel of objects to be tied, as to cause the said guides when opened after the tie has been formed to move out of said plane and out of the path of travel of the objects.

A' further object vof the invention is to provide separable wire guides and carrying means associated therewith acting in conjunction andl combination with formations on a rigid part of the machine for automatically closing said guides when the same are moved into operative position and holding thesame inflexibly closed during the lime-they occupy said position.

In the accompanying drawings illustrating the invention consisting in the specific improvements aforesaid I have shown so much of the object tying machine as will be necessary to a full and complete understanding of the nature, objects and operation of the aforesaid severalimprovements.

In said drawings:

Figure 1 is a view in side elevation of a bag tying machine and an object carrier associated therewith embodying the improvements aforesaid:

Fig. 2 is a fragmentary top plan view of the same.

Fig. 3 is a bottom plan View of the tying machine proper, part of the base plate thereof being broken away.

Fig. t is a vertical transverse section through the tying machine on the line H of Fig. 2.

Fig. 5 is a fragmentary detail front elevation of the tying mechanism.

Fig. 6 is a vlew similar to Fig. 5 on an enlarged scale, the wire guides being shown in transverse section.

.Fig Tris a detail horizontal section on an enlarged scale on the line 7-7 of Fig. 6.

Fig. 8 is a detail vertical transverse section on the line 8 8 of Fig. 7.

Fig. 9 is a View in elevation of the tie as formed by the machine about an object.

The tying machine embodying my improvements includes means for feeding a predetermined length of wire forward at predetermined intervals, means associated withv the feeding mechanism to form the Wire fed by the latter into a loop of a given size and shape, means for clamping the extreme end of the fed portion of the wire to maintain the loop in position after release of the same by the loop-forming means, means for retracting an indeterminate portion of the wire fed to contract the loop about the object and engage the latter with a predetermined and adjustable pressure, means for twisting the looped portion of the wire and the body portion thereof about each other to complete the tie, and means for severing the completed tie from the body vof wire, and

finally forming the key on the completed and severed tie for digitally opening the latter to release the object.

For details of construction of all that part of the tying mechanism not included in my invention reference will be had to the aforesaid applicationA of Rogers M. Warwick,

Ser. No. 9962, but said mechanism will be` suitable. support which is not illustrated said segments being adapted to feed a predetermined length of wire during each revolution of their carryingwheels. The shaft 1 is a stud-shaft carried by a reciprocable member 4 on the bed or table of the machine movable in guides toward and away from the shaft 2 which is similarlv a stud-shaft rigidly mounted in the base plate of the machine. The said reciprocable member 4 is normally held to maintain the wire-engaging segments of the gears carried thereby in engaging relation to the wire.l The latter passes through a tube 5 through the rotatable head 6 to the separable wire guides 7 at the front of the machine, said guides being adapted to cause the wire to be bent to form a horseshoe loop around an object received between the separable lguides 7. Mounted upon a projection 8 on a rigid portion of the base plate of the machine is an anti-friction roller 9 and opposite the same on the reciprocable member 4 is a projection 10 on which a cam'll is pivotally mounted. One face of the latter is main-- tained in contact with the anti-friction roller 9, said face being stepped so that as said cam is turned in one direction the portion of greatest radius of said face will bear upon said anti-friction roller 9 and effect a movement of the member 4 against the action of the springs engaging the same,

thereby throwing the wire-engaging segments carried by the gears on said shafts 1 and 2 out of engaging relation to the wire to be fed forward. A lever 12 is rigidly secured to said cam and projects from the front end of the machine into the path of objects adapted to be tied, and which are carried successively to the tying mechanism by means of the rotatable carrier 13 fully illustrated and described in the aforesaid joint application of said Varwick and myself Serial No. 22,374. A helical tension spring 14 maintains said lever 12 normally in position to cause the portion of greatest radius of the face of the cam 11 to bear upon the antifriction roller 9 whereby to maintain said shafts 1 and 2 separated a distance preventing vsaid wire-engaging segments from operatively engaging the wire to feed the same forward. The said lever is turned by engagement of the object therewith to a position indicated in Fig. 3 whereby the portion of least radius of the cam face becomes opposed to the anti-friction roller 9 whereby the shafts 1 and 2 are permitted to approach each other to cause the wire-engaging segments to operatively engage the wire to feed the same forward to form loop about the object.

The wire lguides 7 -together form what may be termed a horse-shoe shaped device which is separable along the vertical plane extending centrally of the closed portion and midway between the arms thereof. Each member of said guide comprises two parts hinged together and capable of limited pivotal ,movement relatively to each other,.as particularly shown in Figs. 5 and 6. The upper member of each of said parts of said guide is rigid with a substantially semi-circular armA 15 and the lower member 16of each of said parts of said guide is hinged to said arm. The hinge includes 'a projection 17 on `the member 16 coacting with a stop 18 rigid with the arm 15 to limit the opening o r pivotal movement of the members 16 in one direction relatively to the rigid members 7. lThe said arms 15 are secured at their other ends to shafts 19 journaled in bearings above the normal plane of action of the wire guides and at a sufiiciently high lelevation to bring said shafts out of-the path of travel of the object carrier and the objects carried thereby. The said shafts are equipped With seg-v mental spur gears 20 and 21, the latter describing a smallervarc than the former. The said segmental gears are of equal pitch diameter and intermesh, and said gear 2O also meshes with a rack 22 on a reciprocable bar 23 which is actuated from a cam carried by a gear on the shaftn'l, as more particularly shown and described in the aforesaid application of Rogers M. Warwick, Ser. No. 9962, and at proper intervals in synchronism with the wire feeding mechanism and other parts to cause said guides 7 to be separated and raised after each l loop is formed around an object, and remain separated and elevated until the next succeeding object is positioned to be tied. 'l

Each of the members 16 lof the guides 7 is equipped on itslowerface with a projection 24 having an inclined lower face which is adapted to strikethe inclined upper face of a projection 25 ca rried by the uidemember 26 for the wire shearing an key forming mechanism, more fully described and claimed in the aforesaidapplication of 125 Rogers y M. Warwick. As the arms 15 swing to the position to bring the members l of the wire guide 7 together, the said projections ofthe members 16 engage the projections 25 and are thereby forced into 130 their closed positions against the upper members of said guides and are rigidly and inieXibly held in such position whereby to maintain the guide channel closed for properly guiding the wire to form the loop about the object.

For further details of construction and a full and complete description of the operation of the machine embodying my said,

improvements reference will be had to the aforesaid application, Ser. No. 9962, it being obvious that said improvements herein described and claimed are incapable of use in the specific form in which they are herein embodied except in the aforesaid machine of said Warwick, though the same may obviously be modified and varied to adapt them to any variations in construction of the said tying machine, and may probably be also modified and varied in form to perform the same functions in connection with any other machine operating on the same general principles as the aforesaid machine of said Warwick. It will be obvious that the mechanism for preventing feed of wire unless an object is presented to be tied may be utilized in the tying machine in connection. with any mechanical means for presenting the object to be tied.
